GEORGE A. GREENE. OF COOL SPRING, NORTH CAROLINA.

LAM-P-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 240,407, dated April 19, 1881.

Application filed December-22, 1880.

To all whom it may concern Be it known that I, GEORGE A. GREENE, of

Cool Spring, in the county of Iredell and State of North Carolina, have invented a new and Improved Lamp-Extinguisher, of which the following is a full, clear, and exact description.

The object of this invention is to facilitate the extingnishment of lamp-flames, and also to regulate the height of the wicks of lamps.

The invention consists in combining telescoping tubes, a bellows, a loose curved tube, and a tip, as hereinafter more fully described.

Figure l is a front elevation of the device on line 3 3 Fig. 2. Fig. 2 is a sectional side elevation of the same on linear m, Fig. 1. Fig. 3 is a side elevation of the upper end of the device. Fig. 4 is a sectional side elevation of a modification of the device. Fig. 5 is a plan of the head of a thumb-screw.

Similar letters of reference indicate correspondin g parts.

In the drawings, A represents the tubular portion of the device, consisting, preferably, of several tubes, at b c, telescoped into each other, as shown. In the larger, lower, and outer tube, a, is an elongated opening, d, over which is secured a pair of bellows, B, thetube a serving as a handle thereto. The lower end of the outer tube, a, is closed by a cap, f. On the upper end of the inner tube, 0, is fitted a curved tubular prolongation, O, which is free to turn in any direction, and on the end of this prolongation O is fitted a tubular tip, D, that is preferably curved upward to turn the current of air from the bellows B upward.

Secured to the lower end of the prolongation 0, on a side thereof, is the regulator, consisting of an outward-curved rod, E, provided with a forked end, g. This rod E is extended in the opposite direction from the curve of-the prolongation O, for convenience of application to the thumb-screws of lamps.

The rod or regulator E may have a socketed end, or an end of any other convenient form, to apply to lamp thumb-screws for raising or lowering the light by turning said thumbscrews; but when a lamp thumb-screw is of the shape like that shown at F, Fig. 5, the forked No model.)

end 9 to the regulator or rod E is most convenient.

Instead of being secured to the prolongation O, the rod E may be secured to a loose ring or band placed around the tube 0.

The bellows B is provided with an opening, h, corresponding with the opening at in the tube a, through-which openings d h air is forced from the bellows B into the tubular portion A of the device when the tubes 1) c are drawn out. The said bellows B is provided with a spiral spring, k, connecting its top and bottom to keep it open, and with a strap, 2, to keep it from opening too far. Said bellows B is also provided with a suitable valve, m.

The device is held in the hand and the tip D is placed beneath the tube-wick or burner of a lamp. The bellows B is then compressed, and the light extinguished by the current of air forced by the bellows B through the tubes a b c and up the lamp-chimney.

In Fig. 4 is shown a modification of the device, wherein the tubular portion A is a single piece of pipe closed at the bottom by a cap,f, and having a lateral opening, d, with which is connected, by atube, n, a cylinder, G, in which is a piston, 0, operated by a rod, 1), that passes up through a guide or support, g, which projects laterally from the tubular portion A. Said rod 19 is encircled by a spiral spring, r, between the piston o and guide q, that serves to force said piston 0 upward after it has been drawn down by the operator pulling on the rod 19, and thus force the air which is admitted into the cylinderG through its valve m through the tubular portion A of the device.

The manner of operation is to place the regulator E over the thumb-screw of a lamp or burner and therewith turn down the wick, if necessary, and then, with bellows B, force air through the tubular portion A and through the draft-holes of the lamp or burner, and thereby extinguish the light.

The extinguisher may be used without the regulator if desired.

The advantages of this device are that bracket or chandelier lamps can be extinguished by it without mounting a chair, stool, or steps for the purpose, and the difficulty and the telescoping tubes at b c, the bellows B, having opening h, and connecting with the capped tube a f by opening d, the loose curved tube 10 O, and the tip D, as shown and described.
